Embodiment
See also the Fig. 1 that illustrates according to an electrical fitting of first embodiment of the invention, in the hole 2 in being formed at the framework 3 that insulating material makes a pair of end toper spring 1 is installed regularly.Upper and lower volute spring part 1a and 1b and upper and lower end cylindrical portions may 1d and 1e that volute spring 1 comprises an outermost basic circle tube 4, extends out spirally from basic circle tube 4.Be provided with a flange 1c on basic circle tube 4, the edge of a shoulder 2a in hole 2 and a hole 5a of the cover plate 5 that insulating material is made maintains this flange 1c, and like this, volute spring 1 is fixed to framework 3.
Fig. 3 is the expanded view of both-end volute spring.This half-finished shape is roughly Y-shaped.These semi-finished product begin to be wound on the fuse from upper and lower end cylindrical portions may 1d and 1e with the direction shown in the arrow.Two components that tilt form volute spring part 1a and 1b.
Fig. 4 is the profile that the state when connecting electronic equipment with volute spring is shown.Volute spring is arranged between the terminals 8 of the terminals 6 of a microphone 7 and a substrate 10.As shown in the figure, the edge of end cylindrical portions may 1d and 1e and volute spring part 1a and 1b are pressed against on terminals 6 and 8, thereby correctly connect two terminals.
Fig. 5 a is the profile that second embodiment of the invention is shown, and Fig. 6 is the expanded view of this both-end volute spring.Both-end volute spring 11 is fixedly mounted in the hole 12 that is formed in the framework 13.Volute spring 11 comprises an outermost basic circle tube 14, upper and lower volute spring part 11a and 11b and upper and lower end cylindrical portions may 11d and 11e.The edge of the one shoulder 12a in hole 12 and a hole 15a of cover plate 15 maintains basic circle tube 14, and like this, volute spring 11 is fixed to framework 3.
As shown in Figure 6, oppositely extend a component 17 from the end of each spring section 11a and 11b.Place, end at component 17 is formed with a contact portion 18.Contact portion 18 has a plurality of leg-of-mutton protuberances 20, and these protuberances 20 are arranged on the direction perpendicular to the volute spring axis.
Shown in Fig. 5 b, contact portion 18 is wound into a form cylindraceous.Like this, protuberance 20 just can guarantee the connection between the terminals of volute spring and electronic equipment better.
Fig. 7 is the end view that illustrates according to a volute spring of third embodiment of the invention, and Fig. 9 is the expanded view of this volute spring.In these figure, used and the identical label of label among Fig. 1, thereby saved detailed explanation.
Flatly protrude out a retention tab 21 from basic circle tube 4, to be used for that volute spring 1 is fixed to framework 3.On lug 21, be formed with a leg-of-mutton engagement lugs 21a.
